What is the most dangerous parasite?

Inception was so very good. I'd heard it was very complicated and you have to really pay attention or else you'll be totally lost; but actually, as long as you don't zone out or anything it's pretty easy to follow. Structurally, it's very straightforward. There's no HUGE PLOT TWIST -- and that's the brilliant thing. You keep anticipating that "kick", to have the rug suddenly pulled out from under you, but it never happens. The end is so perfect in how it leaves you satisfied but uneasy.

Remember The Prestige? It's one of my absolute favorite movies of all time. I was expecting Inception to be a bit like that, but it's not. Now I can't decide whether I love The Prestige or Inception more.

(spoilers below)...........Weird things:* In the beginning of the movie they were calling Ken Watanabe's character "Seido" and somewhere in the middle they all switched to calling him "Saito".

* Why didn't Cillian Murphy notice that his main business competitor was right there on the flight a few seats away from him? If he's worried enough about 'extraction' that he received special training to defend against it, wouldn't he be get suspicious when his business rival just happens to be on the same flight where he has a bizarre dream that inspires him to dissolve his father's company? And when said business rival actually appears in his dream to direct him? Well, I guess he's not really supposed to remember the dream after waking up. And maybe Saito is more of a 'shadow boss' rather than the public face of his company.

* The bit where Ariadne goes down in the elevator and finds Cobb's wife in the hotel room had a really creepy Sixth Sense-like feeling.

* I thought they established that with each successive dream level time would be stretched even longer, until by the third level a few hours in the real world would feel like ten years? And then they ended up having to scale back their time limit because Cillian Murphy's subconscious was more aggressive than they were prepared for? But in any case, the time they spent in the third and fourth levels of dreaming didn't really seem any longer than the previous levels. And did they really expect to spend ten years running around that Arctic base?

* That whole scene with Tommy from 3rd Rock from the Sun fighting in the hallway in zero gravity? So awesome. I really appreciated that they didn't go overboard with the Matrix-like effects; it felt more real and organic. How the heck did they film that, though? Did they build the set on an airplane and put it in freefall?

* I somehow had the impression that that shore with all the crumbling building cliffs was directly inspired by, or even filmed in, Gunkanjima... but looking at that article again, they don't look all that similar after all. Either I'm mixing it up with some other real life island full of creepy abandoned high-rises, or it was imaginary.

* And in conclusion:

Oh, and I want the soundtrack. That foghorn-like sound keeps playing in my head now.
